Wireless Settings

The Wireless Menu lets you:

•

Configure the Cable Modem/Router to serve as a wireless access point (AP)

•

Configure essential and advanced settings of a wireless network

•

Configure a guest network for temporary visitors

•

Configure WMM QoS

Note:

Your Cable Modem/Router has been preconfigured to support wireless

connections without any further configuration. Please see

Chapter 3: Connecting Other

Devices to your Cable Modem/Router

for details. Most users will not need to read this

chapter.

Description

Select 2.4 GHz or

5 GHz

Select which frequency band you want to set up.

Any setup

changes you make will apply to this band only. For example, if

you select 5GHz any changes you make on this page will apply

to the 5 GHz band only.

Wireless

Select Enable to enable the wireless function.

Country

Your device is configured for operation in the U.S. only.

Output Power

Set the strength of the wireless signal that the Cable

Modem/Router transmits. Most users should use the default

setting. In some scenarios reducing your output power may help

reduce wireless interference. If the Cable Modem/Router is

interfering with neighboring Access Points, reducing the power

level may reduce this interference, causing the neighboring APs

to have fewer retransmissions of their data. This results in less

wireless traffic and less congestion.

Lowering your power level

however will reduce the wireless range of your router.

802.11 Band

This field displays the current band selected.

802.11n-mode

In

Auto

mode, your Cable Modem/Router will automatically

adjust to avoid interference with neighboring devices.

Most

users should use the default setting of Auto.

Bandwidth

Specify radio frequency bandwidth, either 20 MHz single, or

40MHz (dual channel), that the Cable Modem/Router will use

when 802.11n mode is configured as Automatic and the Control

Channel is configured as Automatic. Normally 20 MHz is the

best choice.

Sideband for

Control Channel

(40 MHz only)

You may select Sideband and the secondary extension

channels if your Cable Modem/Router is operating at 40 MHz

bandwidth and the 802.11n-mode is configured as

Auto

. Most

users will not need to change this setting.

Control Channel

Select the channel for AP operation next to the drop-down list

box. The current channel number is displayed. The list of

detailed control channel and extension channels are shown in

the Table below. Most users will not need to change this setting.

Regulatory Mode

By default is Off. Most users will not need to change this setting.

TPC Mitigation

(db)

By default is Off. Most users will not need to change this setting.

OBSS

Coexistence

By default is set to 1 (Enabled). This allows the wireless

bandwidth to fall back from 40Mhz to 20Mhz when the

modem/router detects interference in the area. You may select 0

(Disabled) to disable this feature. Disabling OBSS Coexistence

can result in poor wireless performance if there is interference in

your area. Most users will not need to change these settings.

STBC Tx

By default is set to Auto. Most users will not need to change this

setting.

Restore Wireless

Defaults

Click on the Restore Wireless Defaults button to restore the

Wireless settings.

Transmission

(BFR)

By default is set to Enable. Most users will not need to change

this setting.

Beamforming

on channel 7. The total bandwidth of the signals on channel 11 and 7 equals 40 MHz.

Primary Network

The Primary Network page allows you to configure the primary wireless network and its

security settings. Strong security is the best way to prevent unauthorized wireless

network access. To access the
